Cycle Time

Cycle time is load time (see formulas below).

Load Time for Manual Load = Weight Based Time * Handling Difficulty Factor *

Insertion Difficulty Factor

Load Time for Robotic Load = Weight Based Time

Load time is the time it takes to pick one non-molded subcomponent of a part and place it into the mold or onto an action mechanism. Load time is looked up by part weight in the lookup table tblComponentLoadTime, or specified by the user with the setup option Base Load Time. For Manual Load (see Manual or Robotic Loading), this value is adjusted based on any special handling and/or insertion difficulties. Load time depends on the following:

• Weight based time: by default, this is looked up by part weight and load method (Manual or Robotic) in the lookup table tblComponentLoadTime.

If the lookup table lacks the required data, load time is specified by the cost model variable defaultManualLoadTime (8 seconds in starting point VPEs). Users can override the default, and specify the base load time with the setup option Base Load Time.

• Handling difficulty factor (Manual Load only): this is a factor that accounts for any special handling difficulties, such as those caused by component nesting, stickiness, or fragility.

By default this is 1 (that is, no special handling difficulties are assumed, by default). Users can use the setup option Load time multiplier for handling difficulties to set the factor to a standard value (specified by the cost model variable handlingMuliplier--1.15 in starting point VPEs) or to specify the factor explicitly.

• Insertion difficulty factor (Manual Load only): this is a factor that accounts for any special insertion difficulties, for example, difficulties with alignment and positioning due to obstructed access, obstructed vision, or lack-of-alignment features such as chamfers and lead-ins.

By default this is 1 (that is, no special handling difficulties are assumed, by default). Users can use the setup option Load time multiplier for insertion difficulties to set the factor to a standard value (specified by the cost model variable insertionMuliplier--1.2 in starting point VPEs) or to specify the factor explicitly.
